Abstract
Abstract A pedal plate (13) for a cycle safety pedal (26) is releasably attached to the sole (12) of a cyclist's shoe in the ball region and has a running surface which extends parallel to the attachment region on the sole. The attachment region (11) of the sole (12) is arranged recessed by the thickness of the pedal plate (13) relative to the base surface of the sole (36) around the attachment region (11), so that the bottom of the pedal plate lies substantially flush with the bottom of the sole.
